Abstract

The invention provides a steel tube marking instrument and a using method thereof. The steel tube marking instrument comprises a body which is provided with a fixing groove arranged along the long edge, a sliding block is fixed to the fixing groove, a fixing ring is arranged on the sliding block surface far away from the body, one end of a steel wire rope and the fixing ring are fixed, the other end of the steel wire rope is connected with a marking pen, a guide rod and an adjusting groove capable of containing the guide rod are symmetrically arranged on the body in the direction of the long edge, one end of the guide rod is arranged in the adjusting groove to be connected with a guide plate, a limiting block for limiting the guide plate is arranged at an adjusting groove opening far awayfrom the body, the other end of the guide rod penetrates the limiting block to extend out of the exterior of the adjusting groove, a floating electromagnet is arranged on the guide plate surface deviating from the guide rod, a fixed electromagnet is arranged on the adjusting groove bottom face opposite to the floating electromagnet, the floating electromagnet and the fixed electromagnet are connected with a power source through wires, and electromagnetic fields with opposite magnetic field direction are generated after the floating electromagnet and the fixed electromagnet are powered on. Themarking instrument is simple in structure, convenient to adjust and wide in applications cope.

Description

technical field [0001] The invention belongs to the technical field of pipeline measurement, and in particular relates to a steel pipe marking instrument and a using method thereof. Background technique [0002] During pipeline hot joints and emergency rescue construction operations, such operations as joint cutting of short joints, replacement of welding valves, and replacement of pipe sections due to pipeline defects require high technical quality and short operating hours. During the construction process, operators must The blanking and docking operation can only be completed after repeated measurement and drawing calculations. [0003] In the prior art, multi-point surveying and mapping is usually used to cut the two ends of the pipeline to be connected into a straight pipe when carrying out the unloading and docking operation. The cross-sections at both ends of the pipe have large deviations. When the height difference of the centerline of the pipeline is large, the st...
